CRUDE-OIL BURNER.

SPECIFICATION forming part of Letters Patent No. 710,718, dated October '7, 1902. Application filed December 2311901. Serial M81015; (No man.

To (6 whom, it may concern.-

Be it known that I, JOHN B. SEEGER, acitizen of the United States, residing in Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Crude-Oil Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a burner for use in burning crude oil for fuel purposes, the object of the invention being to construct a burner wherein the oil may be thoroughly atomized and commingled with steam previous to its discharge from the burner, and, further, to provide for the commingling of pure air or oxygen with the oil as it is discharged from the burner.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a longitudinal sectional view'of my burner. Fig. II is a cross-sectional view taken on line II II, Fig. I, through the atomizer of the burner. Fig. III is a cross-sectional view taken on line III III, Fig. I,

through the burner-head. Fig. IV is a longitudinal sectional View taken on line IV IV, Fig. I.

1 designates the head of the bu rner,'provided with an interior crescent shaped mixingchamber 2, that is widest at its rear and center and gradually tapers forwardly to termiof the bu rner-head between the jet-ducts 3 to provide for the passage of air or oxygen from said air-chamber5 through said month, where it mingles with the oil that is discharged through the jet-ducts 3. Pure air or oxygen is conducted to the air-chamber 5 through pipes 7, that are connected to the burnerhead 1 and lead from the exteriorof the firechamberin which the burner is mounted. At the rear end of the burner-head 1 is a neck 8, and extending inwardly into the mixingchamber 2 from the rear end of the burnerhead at the location of said neck are a series of fingers 9.

10 designates an atomizer-box containing an atomiZing-chamber l1 and having a forwardly-projecting neck 12, that is connected to the neck 8 of the burner-head. The neck 12 is provided interiorly With an annular seat 13, and positioned between said seat and the fingers 9 is a spreader 14:, that is preferably of spherical shape and serves to contract the passage through the necks 8 and 12 of the burner-head and spreads the oil as it passes from the atomizer-chamber 11 to the burnerhead chamber 2.

At the rear end of the atomizer-box 10 is a neck 15, that has connected to it a coupling 16, which receives the attachment of a steampipe 17.

18 is an oil-conducting pipe seated in the coupling 16 and extending thereinto. Seated in the oil-conducting pipe within the coupling 16 is a nipple 19, through which the oil is discharged from the pipe 18 into the chamber of said coupling. The oil -conducting pipe has screw-threaded connection with the coupling 16, the thread thereon preferably extending for a considerable distance on said pipe for the purpose of providing for more or less introduction of the oil-pipe into the coupling-chamber in order that the nipple 19 may be projected to a greater or less extent into the coupling-chamber. It is preferably 10-- cated slightly above the horizontal center of said chamber.

20 designates a spider seated in the neck of the aton1izer-box 10 and provided with a central bearing-box 21.

22 is a rotatable sprayer-wheel carried by .a shaft 23, mounted in the bearing-box 21 of the spider to revolve therein. On-the rear end of the shaft 23 isa deflector-cone 24, that occupies a central positionin the chamber of the coupling 16.

In the practical use of my burner the operation is as follows: Oil is introduced through the conducting-pipe 18 into the chamber of the coupling 16 and steam is introduced into said chamber through the steam-pipe 17, the current of steam being directed across the delivery flow of oil, as indicated by the arrows, Fig. I. The force of the steam passing through said coupling-chamber is exerted against the rotatable sprayer-wheel 22, being directed outwardly thereagainst by the deflector-cone 24. By impact of the steam and oil against the sprayer the sprayer is caused to revolve rapidly, thereby finely dividing the oil and commingled steam as it enters the atomizingchamber 11. The commingled oil and steam is caused to circulate rapidly within the atomizing-chamber in a finely-divided spray and continues circulating, as indicated by the arrows, Fig. I, and from the atomizing-chamher the mixed oil and steam passes through the necks S and 12, around the spherical spreader 14, into the burner-head mixingchamber 2, in which the mixture circulates and from which it finds egress through the jet-ducts 3. The force of the ets of oil and steam emerging from the ducts3 in converging directions creates a suction through the mouth 6, leading from the airchamber 5 within the burnenhead, causing the pure air or oxygen entering said air-chamber through the air-conducting pipes 7 tobe drawn through said air-chamber mouth, as shown by feathered arrows, Fig. I, and com mingle freely and in adequate and proper amounts to supply the required mixture of oil, steam, and air or oxygen to produce efficient results in the operation of the burner as requisite.

By contracting the passage-way through the necks 8 and 12 that unite the burner-head and the atomizer-box by the use of the spreader 14, I reduce the space through which the oil and steam in atomized condition passes from the atomizing-chamber to the mixingchamber. By this arrangement the oil and steam are held back, owing to the variation between the entrance-way and exit-way into and from the atomizing-chamber, thereby causing an enforced circulation within the atomizing-chamber in order that the oil and steam will be thoroughly commingled previous to their escape from the atomizing-chamber into the mixing-chamber of the burnerhead.

I claim as my invention 1. In an oil-burner, the combination of a burner-head provided with a jet duct, an atomizing-chamber suitably connected to said duct, a sprayer-wheel located in the entrance to said chamber and a spreader between the chamber and duct for delivering the atomized oil to said duct in a spray.

2. In an oil-burner, the combination of a burner-head provided with a jet-duct, an atomizing-chamber suitably connected to said duct, a sprayer-wheel located in the entrance to said chamber, a deflector-cone below said wheel, and a spreader between the chamber and duct for delivering the atomized oil to said duct in a spray.

3. In an oil-burner, the combination of a burner-head having a crescent-shaped mixing-chamber, an air-box extending transversely of the mixing-chamber, a mouth opening from said box to the exterior of said head, and jet-ducts in said head and directed toward a common center to discharge exterior of the mouth of said air-box.

4:. In an oil-burner, the combination of a burner-head provided with a jet-duct, an atomizer having communication with said burner-head, and a spherical spreader located in the passage-way between said atomizer and burner-head, substantially as described.

5. In an oil-burner, the combination of a burn er-head having a crescent-shaped mixing chamber, an air-box extending transversely of the mixing-chamber, a mouth opening from said box to the exterior of said head, jet-ducts in said head and directed toward a common center to discharge exterior of the mouth of said air-box, an atomizer having communication with said burner-head, and a spreader located in the passage-way between said atomizer and burger-head.

6. In an oil-burner, the combination of a burner-head having a crescent-shaped mixingchamber, an air-box extending transversely of the mixing-chamber, a mouth opening from said box to the exterior of said head, jet-ducts in said head and directed toward a common center to discharge exterior of the mouth of said air-box, an atomizer-chamber having communication with said mixing-chamber, a sprayer located between said atomizing and mixing chambers, and an atomizer located at the entrance of the atomizing-chamber.

In testimony whereof I have hereunto set my hand this 20th day of December, 1901.

JOHN B. SEEGER.
